From: Brian Smith <briansmith199312 at gmail.com> In some cases, when fitting a simple OLS regression, I obtain an estimated beta coefficient that is very small?for example, 0.00034?yet it still appears statistically significant based on the p-value.
to me a statistically significant difference between two treatment groups is always worth reporting, if only because the treatments may have more than one effect. One biological parameter was chosen to be the response but maybe it is not the right one. A small difference is a hint that something maybe more important is going on.
